WebFeb 20, 2024 · The Earth’s field is about 5.0 × 10 − 5 T, and so here B due to the wire is taken to be 1.0 × 10 − 4 T. The equation B = μ 0 I 2 π r can be used to find I, since all other quantities are known. Solution Solving for I and entering known values gives I = 2 π r B μ 0 = 2 π ( 5.0 × 10 − 2 m) ( 1.0 × 10 − 4) 4 π × 10 − 7 T ⋅ m / A = 25 A. Discussion: WebMay 3, 2024 · Solar Orbiter found that Venus’ magnetic field extends at least 188,000 miles behind the planet — about the distance from Earth to the Moon. That’s small relative to Earth’s magnetotail, which extends more than twice that distance.

WebApr 4, 2024 · Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. The signal suggests that the Earth-size planet may... Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun. The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core: these convection curre… green bay calendar of events 2021
